制备了由离子液体1-丁基-3-甲基咪唑溴[bmim]Br和甲醇预处理的高岭土组成的插层纳米材料。我们通过傅里叶变换红外光谱（FT-IR）、X射线衍射（XRD）、热重分析和差示扫描量热法（TG-DSC）、紫外-可见光谱和扫描电子显微镜（SEM）研究了新型插层化合物的一些物理性质。插层化合物显示基础间距从 0.72 nm（对于高岭石）增加到 1.42 nm（对于带有客体的材料）。插层化合物显示出热稳定性的增加。最后，紫外-可见光谱显示该包合物在紫外区域有显着的吸收。
Intercalate nanomaterial comprising of ionic liquid 1-butyl-3-methylimidazolium bromine [bmim]Br and methanol-pretreated kaolinite was prepared. We study several physical properties of the new intercalation compound by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Thermogravimetric analysis and differential scanning calorimetry (TG–DSC), UV–vis spectra and scanning electron microscopy (SEM). The intercalation compound shows an increase of the basal spacing from 0.72 nm (for kaolinite) to 1.42 nm (for the material with the guest). Intercalated compound shows an increase in the thermal stability. Finally, the UV–vis spectra reveal significant absorption in the UV region for this inclusion compound.
